Why was Moshe told to first anoint the Ohel Mo'ed and the Aron, bypassing all the Keilim in the Heichal? Why was this not considered a contravention of 'Ein Ma'avirin al ha'Mitzvos'?
1.
Oznayim la'Torah: Because, since the purpose of the anointing was to sanctify, it was correct to begin with the Keilim which were the most holy - giving overall precedence to the Ohel Mo'ed even to the Aron ha'Kodesh, since it held and incorporated all the Keilim.
